LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 353,674, dated December 7, 1886.

Application filed November 18, 1885. Serial No. 183,236.

To all whom it may concern.-

Be it known that I, ADOLPH GEIss, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a full and complete description, when taken in connection with the drawings accompanying the same.

My invention relates to the class of lamps where a circular flame is produced, the air support-ing combustion in said flame being supplied both to the inner and outer surface thereof, and commonly known in the art as central-draft lamps.

The object of my invention is to produce a burner of the class named,which may be readily applied to an ordinary lamp-globe or oilchamber, in the same manner as ordinary burners are applied thereto, thus securing a flame of the desired character and power without other change in said lamp.

For the purpose of constructing a burner of thekindnamed and for the purpose designated, I make use of a flat wick surrounding a central tube and held closely to said tube at and near the top thereof by an outside tube, the said wick passing around an opening in said central tube, through which air is supplied thereto from the chamber, hereinafter more fully described, in the lower portion of said burner. I am aware that a flat wick and a central tube to which air is supplied through an opening therein have heretofore been used.

It is my purpose to use my improved lampburner in lamps of different sizes, and for that purpose I make use of the ordinary diminishing coupling, so called.

I have illustrated my invention by the drawings accompanying the same, in which Figure l is a cross-section of the completed burner. Fig. 2 is a cross-section of the wickraising device and the central tube and lower outer wicktube. Fig. 3.is a sectional plan view on line 3 3 of Fig. 2. Fig. at is a perspective of the wick-raising device. Fig. 5 is a plan of the perforated gauze forming top of the central tube.

Like letters refer to like parts throughout (No model.)

Y is the diminishing-collar. Z is the upper portion of the globe or oil chamber of a lamp.

WV is an ordinary wick-raising ratchet and thumb-piece.

A is the central tube, having opening a. therein.

B is an outer tube surrounding tube A,and extending from about the lower end of tube A to about two-thirds the height of said tube A. The precise height of tube B is not material, provided it extends sufficiently far to allow opening a through said tube B and tube A to be properly made and cased for the admission of air into said tube A. The wick used passes between said tubes A B and around opening a.

a is the gauzecovering top of tube A.

a is the bottom of tube A.

a is a hole through bottom a.

O is a post firmly secured to bottom a of tube A. The post 0 serves as a journal-bean ing for the inner end of wick-ratchet W, and also for a support to wire D.

D is a wire or other suitable post, secured at its lower end to post 0, and passing through gauze .a, serving at its upper end for a support for air-spreader X. Post D also forms a guide and support for wick-rack E.

D is the wick holder and raiser, consisting of Wiclerack E, posts F F, united at their lower end by bar or tie F, and at their upper ends by toothed ring F.

G G are grooves in tube A, into which posts F F move.

Wick-raising rack E passes through hole a in bottom a of tube A, fitting loosely therein, but guided thereby.

H is thetube surrounding tube A at its upper end, and forms the outer wick-tube. TubeH is held in position by perforated plate Lwhich extends from tube H to the tube J, forming the outer wall of air-chamber K. Tube J has perforations in the lower part thereof for the admission of air to chamber K.

L is a ring surrounding tube B at the lower end thereof. Tube L forms the bottom of air;-

chamber K, when tube J, having tube H secured therein, as described, is placed over tubes A and B, the lower end of tube J therefore fitting over ring L.

In order that the tube J may be the more firmly held in position, and alsoto prevent the dripping or leakage from the wick into airchamber K, tubes B and H fit closely together, one of said tubes extending ashort distance into the other of I said tubes. I

M is the dome.

N is the chimney-support.

The manner of operation of my improved burner is as follows: The wick is passed between tubes A and B, and brought closely around ring F, and tubes J and H are then placed in proper position over said tubes A B. Wick-raising device D may now be raised or lowered by ratchet and wheel W, thus raising or lowering the wick. The air supplied to the flame of the lamp enters air-chamber Kthrough the perforations in tube J. That portion supplied to the outer surface of the flame passes through perforated plate I, and the portion supplied to the inner surface passes through opening a into tube A,and through perforated gauze a. The air passing through perforated gauze a is deflected by air-spreader X. Any gases generated in the oil chamber Z pass through hole a into tube A, and, together with the air supplied said tube, pass through gauze a.

Having thus described my invention and the manner of its operation," what I claim, and desire to secure by Letters Patent of the United States, is

1'. The combination,with an Argand burner,

of wick-raising device 1), consisting of rack E, posts F F, tie F, and ring F, with post D, and ratchet and wheel W, all substantially as described, and for the'purpose set forth.

2. The combination,with an Argand burner, of .wick-raising device D, consisting of posts F F, tie F, and ring F, and rack E, with an inner wick-tube having an aperture in the bottom thereof,and grooves therein in which said posts F F are moved and guided, all substantially as described, and for the purpose set forth.

3. The combination, with an Argand burner, of a wick-raising device consisting of posts F F, tie F, ring F,post D, rack E, and ratchetwheel W, with a tube having grooves therein,

and a post in the center thereof, serving as guides for said wick-raising device, all substantially as described,and for the purpose set forth. 4. The combination,with an Argand burner,

of a wick-raising device consisting ofposts F, tie-rod F, ring F, rack E, and inner wick-v tube having grooves therein,and a post in the center of said wick-tube, the said rack provided with a guiding-clasp engaging said post, and said post also extending beyond said tube, and an air-deflector placed thereon, substantiall y as described.
